It is classified as a vulnerable species, with 5 of the`9 polar bear subpopulations in decline. They have a reputation as the only animal that actively hunts humans, but in fact, anything they encounter is potential prey.

Does a polar bear have any defenses against its predators?
The polar bear does not have any predators. It is at the top of the food chain.
the only enemy a polar bear has is man, they will hunt them down for their fur and think they look good as a rug!
The native people will also hunt polar bear, but they will use every part of the animal for food and clothing.
The polar bear can only avoid man by trying to camouflage into the ice and snow, and swim under water.
There at the top of the food chain
almost to the top. Humans are on top of the food chain.
What type of skin covering do polar bears have?
The polar bears have and insulating undercoat as the covering of their skin. This is the topped up by hairs which will protect the undercoat.
Is polar bear an amphibian or a terrestrial or aquatic?
The polar bear is found in the Arctic Circle and the nearby islands. They can be found in good numbers in Alaska, Norway, Denmark, Russia and Canada. There are smaller populations in the surrounding regions near the Arctic pole. They prefer the Cold Icy areas of the Arctic and thrive in areas where the human intervention is minimal. They are found in good numbers in areas where their primary prey, the Seals mate and nest.
What insulation do polar bears have?
Polar bears have translucent guard hairs. They are shaped like hollow tubes. They are between 5 to 15 cm long. Underneath the guard hairs is a thick insulating undercoat. They have stiff hairs on the bottoms of their paws that aid with traction when walking on ice. The males also have ornamental hair on their forelegs.

Where does a polar bear sleep?
Polar bears sleep wherever they are able to be out of the water. Caves; on the surface of the sea ice; on land; on a floating tree -- if:
a) the polar bear can manage to balance its sleeping body on the tree, and
b) there is actually a tree floating where the polar bear needs it.
Polar bears do not hibernate; it is a "dormant state" which is similar to hibernation, but not actually the continuous, deep sleep of real hibernation; it is the same as a human sleeping up to 20 hours each day.
In autumn ("fall"), pregnant female polar bears that are ready to give birth will dig a den out of the ice or snow, or the permafrost if it isn't cold enough for snow, on land. It is in the den that female polar bears go into the "dormant state".
Polar bears slepp like people teeter lol I am 4 but I know how to spell on computer jk I am 10 real
What type of feet does a polar bear have?
Polar bears have bumps on the pads of their feet to keep from slipping on ice. They also have long hairs between the toes for the same purpose.
What is the polar bear's role in its ecosystem?
Habitat
Though they are excellent swimmers, polar bears spend most of their time atop Arctic sea ice. Sea ice is an ecosystem in itself, supported at its base by plankton and algae at the bottom of the food chain. Polar bears share this habitat with seals, whales, Arctic foxes, birds and even people.
Pr Predator
Polar bears are the primary predator in the marine ecosystem of the Arctic. They mainly hunt seals and the occasional young walrus or whale. Polar bears mostly eats the fats of their prey. Birds, seals, walrus. In times of scarcity, they eat anything available, including fish, reindeer, birds, rodents, eggs, kelp, berries and even garbage.
Why are polar bear populations going down?
The primary food source for the Polar Bear is the seal, which they hunt from the ice. As global warming melts the arctic ice, the Bear's hunting grounds diminish, thus threatening their existence.
Why is a polar bear's skin not black?
Yes, Polar Bears have black skin, but most people do not know this because they have colorless fur (not white...). You can see this is true by looking at the nose of a polar bear, where the fur is thinnest, and you will see that it is black.
How does a polar bear adapt to its environment?
They hibernate to avoid the effects of extreme cold, they stand in river water to fish, they claw downed trees apart to search for termites and grubs, and they dig up roots to eat. They also ignore honey bees while the raid for honey is on!
Do Siberian tigers eat polar bears?
NO. Tigers don't live where polar bears do, so the question has no merit whatsoever.
How are polar bears different from camels?
People can ride camels and use them to carry goods, if a person tried that with a polar bear the person would probably be eaten.
Why do polar bears eat and sleep to maintain homeostasis?
Because the habitat of polar bears is a hostile freezing environment, they need to conserve every bit of energy to maintain normal body temperature. Hence, these animals doÊactivities as less as possible so as not to waste energy. After they hunt and eat, they will spend the rest of the day resting and sleeping.
What are the environmental threats to the polar bear?
- Concentration of other bears,
- Availability of food resources,
- Conditions and locations of the ice pack,
- Relative location to human populations,
- Ocean currents under the ice and how that affects the location of food populations like seals,
- Environmental changes in season lengths (which affects duration of ice pack and food availability)
How many polar bears have been saved so far?
no one knows how many have been killed. but we do know this. that 20000 polar bears are left in this whole world.
What does the energy pyramid of polar bear look like?
There is no energy pyramid on the continent, because there is no food chain on the land.
However, the Southern Ocean which surrounds the continent, has the shortest food chain on Earth, based on Antarctic Krill, properly Euphausia superba. The top of the ocean's food chain are protein-consuming whales and seals.
In the winter, when there is little to eat,a bear's heart rate slows down. Bear's don't eat or drink anything over the frostey winter. A hibernating bear can lose up to half of its body weight over the winter
What do polar bears eat in summer and winter?
Polar bears eat next to nothing during the summer time. They may try to catch a few lemmings, some birds and eat some birds eggs, but other than that they're waiting around until winter comes back again.
During the winter polar bears feast on seals, walrus and some whale.
What do female polar bears do to protect there cubs?
Well, that would be very rare since animals aren't like human beings and they kill other living beings for food and they don't go bankrupt, but hypothetically speaking if a mother bear couldn't get enough food they would probably survive on plants and bugs and whatever they can find, humans don't differ from animals as much as you may think, they gotta do what they gotta do to survive, until they seek a better life and they would probably drink dirty water, and if that certain cub was eating too much the cub would probably help the mother bear hunt.
Hope I helped!

How much blubber do polar bears have?
The average Polar Bear will carry about 3.9 inches, or 10 cm of blubber to help insulate them in their cold climate. Their fur, and hide is also designed to help protect them from the temperatures, and harsh extremes. For more details please, see sites listed below.
Will the polar bears survive after 10 years?
Polar bears are currently on the threatened species list. Reports show that if conditions do not improve, the polar bear could be mostly extinct by the year 2050. However, if we actually acknowledge this problem, the polar bears will stay around for much longer.
Who are polar bears predators?
Polar bears are typically the ultimate predator in their habitat, and nothing else preys on them. They do sometimes fight among themselves, and males may fight to the death over the right to mate. Young polar bears are preyed on by other animals, such as wolves and cougars. Humans also kill polar bears, and killer whales will catch and eat swimming polar bears if they can.
